List: 2,000 pt GK for WargamesCon...Decisions, decisions.

Hola Internets!  As most of you know I have been diligently working on my new Grey Knights army (2000pts) for WargamesCon.  However, after having more quality time with the book I think that I have found a new army list that I like more than my current one.  Help me decide which army to take!

RAS+DEV= Spam and cheese sandwich?

So I decided to write up a new list. Let me know what you think. (2000 pt Blood Angels)
